Specification of Letters Patent. Patented Mar. 22, 1910- Application filed November 10, 1906, Serial No. 842,772. Renewed January 5, 1910. Serial No. 536,483.

1711011 whom it may concern:

. Be it known that 1, CHARLES B. PHILLIPS, a citizen of the United Statem'atnd a resident of Blissfield, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Cream- Se arators; and 1 do hereby declare the f0 owing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it I appertains to make and use the same, reference being had to the accompanying drawing, and tothe figures of reference marked thereon, which form a part of this specification.

My invention relates to apparatus for separating cream from milk, and it has for its object to improve upon the construction of apparatus of this class, and particularly the construction covered by my former United -l ig. 3 is a cross-section on the dotted line w w in Fig. 1, and Figs. 5, and 6 are d fferent views of modified forms of the disks.

. Referring to the drawings, 1 designates the revoluble cylindrical bowl or shell forming the separator chamber of a creamer, theremovable top thereof, which is of conic'al shape and has the usual outlets for the milk, as atQf, and for the cream, as at 2", and '3 the axial feed-pipe or tubular shaft .through which the'milk is supplied to the -separating-chamber and which'communirates with said chamber through lateral openings 4 in its lower end;

Surrounding the feed-pipe 3 within the bowl lflare arranged a 'lurality of super"- iinposed disk like mem ers or shelves 5, which are removable therefrom for'the pur pose of cleaning and either rigidly spaced.

apart y 'Ivertical' ribs "or strips 6 or any concussion.

other by the legs 7, as shown in Fig. 4, thus enabling them to be separated from each other. These disks are preferably conc'aved ported in suitable spaced relation above each with their conveX'ed surfaces uppermost, and

are spaced'so that the lower. edge of each is disposed a short distance above the upper I surface of the disk next. below, substantially as shown Each disk has its outer edge or periphery flush with the casing 1 so the milk cannot pass thcrearound, and all are provided with openings 8 concentric to the feed-- pipe or shaft 3. The size of each opening i is slightly. increased over that of the opening in the disk next below, so that the milk as it passes upwardlythrough the outer portion of each opening is permittedto escape the cream zone which gradually increases in thickness from bottomito top of the separator-chamber. This feature is very essen tial to the proper operation of tln creamer as it is important that the milk in its upward moveincntshall not have an agitating contact with the stratum of cream surrounding the feed-pipe or shaft 3, as the particles of cream must not be broken or sub ected to The lower disk 5 of the set is provided adjacent its outer edge with a plurality of small openings or apertures 9 through.

which the milkis caused to pass in its ascent after being discharged to the separatorchamber from the lower end of the feed pipe or tubular shaft 3. Y

The feed-pipe or shaft 3 is provided longitudinally thereof with a plurality of radiating wings or flanges 10, which turn with the shaft and casing and combine with the ribs or strips 6 to impart a whirling cen trifugal movement'to the milk. In order to prevent the disks 5 turning relative to the shell they may be locked thereto by one of the ribs or strips 6 being radially broadenedto form a key which coacts with a groove in the casing, as shown at 11 in Fig. 3, or they may be' secured a ainst relative movement in any other suitab tent manner. r

In'the operation of my improved creamer the shell or separator-chamber is revolved in any suitable-manner, and the 'milk to be acted on fed-thereto through the feed-pipe 1c or convenor tubular shaft 3, which revolved with the .shell. The milk as'it is discharged from the lower end of the shaft is forced through the openings 9 i11 the lower disk 5 into the by the contact of the milk therewith.

compartment next above, thence through the central opening 8 therein, but outside of the cream stratum, which, due to its lower specific ravity, now begins to separate from the revo ving milk and hug the wall of the feed-pipe 3, and so onthrough each superimposed compartment and disk opening until the top of the chamber is reached, where the separated milkand cream are conducted away through different channels. As the milk enters each compartment formed by the several disks it is caused by the centrifugal force acting thereon to move to the outer portion of the compartment, i while the impelling force behind causes it i to strike the concaved surface of the diski next above and approach the center of the l compartment in order to find an exit therei fiom through'the opening 8 in such disk, thus causing the milk to follow a zig-zagl course, as indicated by the arrows in Fig. 1, whereby to thoroughly extract the cream particles therefrom. It is found by the l arrangement of the disks,as shown, that the i repeated bacluvard and forward action of 1 the milk causes a more perfect separation of the cream than is possible with other l types of hand creamers and that thegradually increasing cream stratum is not broken or subjected to any injurious concussion While I have described the disks 5 as bei tel-s Patent, is.-

; within the ing concaved in form, I do not wish to limit myself to this form, as a plurality of flat disks 12, as shown in Figs. 4, 5- and 6, may be employed if desired. It is preferable, however, to use the concaved form of disks,

as the eddies which would be formed at the 5 sharp angles at the outer lower edges of the flat disks are avoided with the concaved 5 construction of disk.

Having thus described my invention, what I claim as new, and

In acreamer, a revoluble bowl, a plurality of spaced superimposed disks having their peripheries flush with the bowl sides and curved downwardly to prevent eddies at such points, each disk; having a central opening of greater'diameter than that of the disk next below whereby the cream zone is gradually enlarged from bottom to top thereof. and a feed-pipe disposed axially bowl and extending through the disk opei'iings with its discharge at the bottom of the bowl.

'In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
